When Rita was making an unofficial Take Your Son to Work Day to entertain her son Lincoln Loud because Lynn Loud Sr.'s workplace had Take Your Daughter to Work Day, she introduced him to Fisher and asked Lincoln to feed him.
Lincoln found Fisher dull because he was expecting a piranha, barracuda, or Great White shark, so, to make feeding Fisher more interesting, he pretended he was a fierce predator.
While doing so, Lincoln accidentally gave Fisher too much food and, while taking the excess food out, Fisher jumped out of the tank, through a trunk, through Lincoln's pants, and eventually back into his tank.
The Hog is an unnamed minor character in The Loud House.
In "Pulp Friction", the hog is seen in the pickup truck along with the farmer.
The hog has light pink skin, and a darker pink nose. While riding Lynn's bike, he wears a red, yellow, and blue bicycle helmet.
After Seymour's croaking made Lola messes up her makeup, she decided to take care of the problem herself, or at least Lana thinks. It is unknown if he was real or not, because in the end, it turned out to be a prank for Lincoln set up by Lola, because he was using noise-cancelling ear buds and the flashbacks could have been fake or real.
Despite the stories being made up, it appears Seymour may have actually been real. Seymour's name (which was misspelled as "Seymoor") was taped on a tank that Lana kept him in her room. After the story to the frog fiasco ended, it's shown that Seymour's name was covered up by a label for Lana's new lizard Izzy. Lana still seems to hold some feelings of despair over the loss of her frog, and hates to bring it up.
Considering the frog fiasco was made up, it is likely that Lola never did anything to Seymour, as Lana admits she can't prove she did, and his true fate is currently left unknown. Whatever really happened to the frog or if the frog even ever existed remains a mystery.
It would appear that Seymour was Lana's first pet frog, and that she had him before Hops. But since it is unknown if the frog is real or not, it is unknown if this is true.
Seymour is a standard looking green frog.

When Lisa was hiking through the national park with her family, a giant egg fell down, and she spotted an owl with antlers. At the news report, right after she showed the Park Ranger, the Dowl's antlers fell off, and revealed that the antlers were fake, as they have a sign on them that says "Made in China". The Park Ranger told the truth, explaining that he bought the antlers from a yard sale, and glued them on the owl. It was his attempt to try and get people to come to the park, as not many people come anymore, because the local geyser was inactive.
The Dowl is a regular owl, with deer antlers glued onto its head.
